To demonstrate the performance of color image processing algorithms, it is desirable to be able to accurately display color images in archival publications. In poster presentations, the authors have substantial control of the printing process, although little control of the illumination. For journal publication, the authors must rely on professional intermediaries (printers) to accurately repro...

color halftoning, dithering, barycentric coordinates. Monochrome dither halftoning is a gray-scale image rendering procedure where gray-levels in an image are compared against a periodic threshold array, placing a Black dot in every location whose gray-level is smaller than the corresponding threshold value. Current generalizations to color printing result in Cartesian thresholding procedures, ...

Despite the widespread availability of color cameras and color displays, there is still a demand for black-and-white imagery due to three main factors: (1) artistic effects (e.g. Ansel Adams), (2) the cost gap between color and black-and-white printing, and (3) the design of many algorithms in image processing and computer vision that require a single value per pixel. Recent research [Rasche et...

The idea of using pseudo-random spatial structures in graphic arts (color and black&white rendering algorithms) was suggested by psychologists and biologists about ten years ago. They observed that some natural pseudo-random structures such as the spatial distribution of receptors in the human retina play an important part in the perceptual process. Our modelization of pseudo-random spatial str...

1 Overview This document provides a detailed discussion of the plotting functions in marray package, which is a packages for diagnostic plots of two-color spotted microarray data. This docuement provides functions for diagnostic plots of microarray spot statistics, such as boxplots, scatter–plots, and spatial color images. Examination of diagnostic plots of intensity data is important in order ...

Abstract In this paper, we propose Color2Hatch, a decolorization method for business/presentation graphics. each region represented as closed path and uniformly colored in scalable vector graphics (SVG) is converted to hatched black white. From the characteristics of business graphics, hatching patterns are designed represent mainly hue region; additionally, lightness saturation can also be ref...

Journal of Digital Information Management Volume 9 Number 6 December 2011 ABSTRACT: Color consistency is one of the key techniques for color marketing in color reproduction in network transaction system. A new color management method is presented based on analyzing the color rendering principles of scanned input images. Firstly, the method substitutes color blocks in color shade district in sta...
